[. . . ] SPR - 20 owneR'S manual SPR - 20 owneR'S manual The S P R - 2 0 F e a t u r e s · Provides an ultra-stable 120 VAC supply from low or high voltage sources · Linear Filtering Technology for unequaled audio / video clarity · Series Multi-Stage Protection provides virtually maintenance-free AC surge suppression · Cool running, noise free technology allows placement in critical listening environments · Detachable surge suppression module for telco and cable / satellite connectors · 20 amp RMS capacity SPR - 20 owneR'S manual Introduction For over 30 years, Furman has pioneered the development of AC power products for the most demanding audio, video, and broadcast professionals. Though the need for stable AC power is nothing new, the SPR-20's technology and its unique implementation is revolutionary. 20, home theaters are supplied with constant, virtually unwavering AC voltage. This assures trouble-free service for any environment suffering from unstable power. The SPR-20 generates virtually no heat, and produces none of the mechanical noise typical in inferior AC voltage regulators. [. . . ] The third screw used for each rack ear is for the center hole, located towards the rear and aids in stabilizing the unit when rack mounted. Connection: aC Cable Routing Once the SPR-20 is placed, its AC cord's female end must be plugged into the male IEC connector located on the lower left hand side of the rear panel (when facing the rear panel). Next the male Edison plug must be connected to an appropriate socket (see current rating recommendation above). Connecting Components to the Digital Video Component aC outlet Banks The SPR-20's four "Digital - Video Component AC Outlets" should be employed for critical video components such as DVD players, projectors, Plasma, or LCD video screens. When employing the SPR-20 for a 2-channel audio system, a pre-amplifier and or CD player would be ideally suited for these outlets. Connecting Components to the linear Filtering Power Banks The SPR-20's eight rear panel, and one front panel, Linear Filtering Power Outlets should be employed for any component not connected to the four "Digital - Video Component AC Outlets. " These outlets still posses incredible AC noise filtering to maximize system performance. Soft Start - Continuous use and Break-In Time When power is first applied to the SPR-20, (the front panel breaker- power toggle must be switched to the "on" position) the Soft Start feature is activated. There is an audible "clack" when the SPR-20 is first turned on or off. This sound is produced by the Soft Start circuit's 30 Amp relay engaging or disengaging. There is virtually nothing in the SPR-20's construction, design, or componentry to wear over the life SPR - 20 owneR'S manual time of the product, and there is no power draw from your electric service meter aside from the LED power indicator, and relay circuits. For this reason the SPR-20 may be left with its power engaged permanently at a cost of pennies per month. This is an added benefit, as many audio/videophiles find performance improves significantly when leaving lowpowered components permanently charged (turned on). Though it will function flawlessly right from its shipping carton, the performance of its circuit parts will improve after approximately two weeks of continuous use or "break-in. " Protection oK Indicator: Although the Furman SMP circuit assures virtually maintenance free protection from transient voltage spikes and surges, nature has a way of occasionally creating electrical forces that are beyond the capabilities of any Transient Voltage Surge Suppression device to absorb without some degree of damage. In the rare instance that this occurs, the blue LED located in the center of the front panel will dim, even though AC power is present at the unit's outputs. If this happens, some level of protection from voltage surges will remain, but the Furman's clamping voltage rating will be compromised. The unit must be returned to Furman Sound, or an authorized Furman Service center for repair. NOTE: If the mains power is above the high cutoff voltage and has caused the unit to remove power from its outlets, it cannot restore power without the operator manually turning the unit off, then on again. Avoid turning the unit back on, without first checking the source of the problem, and perhaps changing the AC source. Telco ­ Satellite ­ Cable Transient Voltage Surge Suppressors The SPR-20 features transient voltage surge suppression for both standard telephone lines, as well as cable or satellite lines utilizing standard coaxial connectors. As these surge suppressors are in-line, they will require an additional cable to connect from their output to the control device requiring protection. All in-line surge suppressors feature our exclusive ground contamination free technology. This aids in eliminating audio buzzing, and the video hum-bars that can result from typical in-line suppressors. Further, our cable and satellite suppressors are TIVO friendly as well as aC Transient Voltage Surge Suppression and extreme Voltage Shutdown extreme Voltage Shutdown Indicator: This LED is normally off. [. . . ] All Furman Surge Protectors must be plugged directly into a properly wired AC power line with a protective ground and must not be "daisy-chained" together in serial fashion with other power strips, UPS's, other surge protectors, three-to-twoprong adapters, or extension cords. Any such installation voids this warranty. The Furman warranty only protects against damage to properly connected equipment where Furman has determined, at its sole discretion, that the damage resulted from an Occurrence and does not protect against acts of God (other than lightning) such as flood, earthquake, war, terrorism, vandalism, theft, normaluse wear and tear, erosion, depletion, obsolescence, abuse, damage due to low-voltage disturbances (i. e. brownouts or sags), non-authorized program, or system equipment modification or alteration.
